Why camera_record needs a policy

This tool modifies the camera recording state (on/off) on the printer, which is a reversible configuration change. It does not execute code, delete data, or involve financial transactions. Misuse could enable unwanted surveillance or disable monitoring during a print job, but the effects are reversible.

From the tool's definition Enable or disable camera recording on the printer

POLICY

How to control camera_record

PolicyLayer is an MCP gateway — it sits between your AI agents and Bambu Lab MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for camera_record:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "camera_record": {
      "limits": [
        {
          "counter": "camera_record_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

camera_record stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
